Is automatic social bookmarking worthless?

I have used automatic software for bookmarking but I have not got good effects. Even, no bookmarking is helpful for me.


After posting a blog, I started bookmarking but it has not given me even single traffic.


Are you all getting traffic from automatic social bookmarking tools?


Even, I have got traffic from manual submission in higher social sites which are popular in the market. Automatic bookmarking software claims for submitting site in top social bookmarking sites but they are fail for providing quality work.


Do you know any automatic software, which really submits in reddit, stumbleupon, newsvine, digg and other top sites?

I doubt about that. Because most of the popular social bookmarking sites don't allow bots to post.
I always do auto social bookmarking but only to get a valuable links from them. But i usually post on the popular 5/6 SB sites manually from where i get a good amount of returning visitors.
thanks

Automatic Bookmarking Tools not Quality able ,Many links Notwork Should you Manuall submesson and use high pr links and do-follow

I would rather submit to a few hundred pligg sites and get the mixture of do follow / no follow backlinks than post to 3-4 "top" SB sites and get a few clicks, just my 2c. I guess to each their own.
